Much is being said about climate change and global warming. One question often asked is "What is the difference between climate change and global warming?" The answer is quite simple - global warming is occurring and the average temperature of the earth is rising and is expected to continue to rise for many decades. The key word in the previous sentence is "average". Although the average global temperature will rise, the effect will be different for some areas of the world. The United Kingdom is one of the places where average temperature could fall. Thus, in the United Kingdom, the term "climate change" is more usually used in preference to "global warming".
